The village of Moodus, in the town of East Haddam, gets its name from the Indian word, “Machimoodus” which
means “place of noises” (Roberts 1906:86). In the area of Cave Hill and Mt. Tom in Machimoodus State Park, there
are reports that go back centuries of these legendary noises.

It is said that the Native Americans believed the noises were the work of Hobomocko or Satan, and held powwows.
“From the earliest of inhabitants of this region, the people of the Pequot, Mohegan and Narragansett tribes, the
thundering and quaking around Mount Tom were evidence of the living presence of the god Hobomocko, who sat below on a
sapphire throne and decreed all human calamity” (Philips 1992:201). Further, “Connecticut Indians depended upon
the local Machimoodus tribe to interpret the many voices of the evil deity” (Philips 1992:199).

Just as the Native Americans feared these noises, they also spooked the first Europeans. Even into the 18th century,
some people believed that the cave at Cave Hill gave direct access to the realm of Hobomocko (Philips 1992:201).

By the 19th century, a scientific point of view was taken as to the cause of these noises. It was thought
that maybe these noises were seismic disturbances. Finally in 1981, scientists studied the area. They “used a series of
special underground sensors to monitor for seismic conditions; otherwise, the earthquakes are too small to detect”
(Hartford Courant 15 Aug 2007: B.2.). They detected over 500 microearthquakes over a 3-month period (Hartford Courant 15
Aug 2007: B.2.). These small quakes produce audible sounds, and hence the strange Moodus noises that have been reported
near the confluence of the Moodus and Salmon Rivers in the Cave Hill and Mt. Tom area.

In May of 1791 a quake occurred in this area with its epicenter in Moodus. It created heavy damage, knocking
down chimneys, toppling walls and leaving fissures in the ground. Scientists estimate that the quake would have registered
a 4.3 on the Richter scale (Hartford Courant 25 Mar. 2011: B.1.).

There have been smaller quakes since then, measuring around 1.3 on the Richter scale. Noises being emitted have
been described as “cannon fire,” “a heavy log rolling,” “a clap of thunder” and “the passing of a heavy truck”
(Hartford Courant 15 Aug 2007: B.2.). In March 2011 there was an incident of explosive sounds that shook houses and sent
out emergency personnel, the cause of which was verified as a small tremor or quake (Hartford Courant 25 Mar. 2011: B.1.).

A day trip to both Machimoodus State Park and Cave Hill is a day well spent. This State Park offers hiking, horseback
trails and cross-country skiing in season. You can enjoy all this natural beauty while you’re thinking about the myths
and legends that go with this area.

I found the cave at nearby Cave Hill a unique feature. My visit made me realize that this isn’t some exaggerated
nook or cranny; it is a narrow but deep cave. As can be seen in Photo 1, the cave has a sizable entrance that you can
easily enter without having to crawl; just little stooping required. Once inside the cave, Photo 2 shows its depth; it
appears to enter into the abyss. It reminds me of what a doctor sees when he’s examining your throat. It would be
interesting to see how deep it goes, but I found no reference to anyone ever probing the cave’s depth. Photo 3 gives you a
perspective from inside the cave looking out and again the size of the entrance.

Interestingly, in the same rock formation of the cave there are also two rock-shelters, one very large in size (see
Photo 4). In this rock over hang, all that is needed is something such as wood to cover the front to make this natural
formation a living space. I remember an archaeology instructor lecturing many times that if you come across a rock-shelter
you have an archaeological site. Native Americans and early European settlers used rock-shelters as living quarters.
